Loxaulus championi (agamic)

Loxaulus panamensis (agamic)

Loxaulus championi Medianero & Nieves-Aldrey sp. nov. (Figs. 1, 2 & 5A–D)
    
Etymology. Named after George Champion (1851–1926) English entomologist, collector of the first cynipid galls from Panama.

Gall (Fig. 5C–D). Elongated slight swellings of twigs (Fig. 5C). The gall surface rough, of the same colour as the bark. The swellings have at least two times the diameter of a normal stem. Larval chambers are arranged longitudinally in rows under the surface of the bark (Fig. 5D). The galled stems are barely recognizable before the emergence of the adults. 

Distribution. Loxaulus championi was found between 2400 and 2700 m a.s.l. at Volcan Baru, Chiriqui, Panama.

Biology. Only the asexual generation is known, inducing galls on Quercus bumelioides Liebm. (section Quercus). The galls are found between July and December during the rain season in Panama.

Loxaulus panamensis Medianero & Nieves-Aldrey sp. nov.

Etymology. Named after the country where the new species was collected.

Gall (Fig. 5G). Cryptic, polythalamous in twigs. There is a only a slight stem hyperthrophy and the galls arebarely detected before adults emergence. The gall consist of small ellipsoidal larval cells inside of twigs.

Distribution. Loxaulus panamensis was found to 3079 m a.s.l. at Volcan Baru, Chiriqui, Panama.

Biology. Only the asexual generation is known, inducing galls on Quercus bumelioides Liebm. (section Quer-cus). The galls are found between May and July during the rain season in Panama

Two new neotropical species of oak gall wasps of the genus Loxaulus Mayr (Hymenoptera: Cynipidae: Cynipini) from Panama.
